3D diamond detector is a relatively new concept that is characterised by an electrode array fabricated inside a Chemical Vapour Deposition (CVD) diamond plate using a femto-second laser, resulting in electrically conducting graphitic paths. This fabrication method allows for various complicated electrode structures, making it possible to design novel electrode geometries and optimise the...
The increase in luminosity at the HL-LHC has led to the need for both increased radiation resistance in particle sensors, along with the need for timing capabilities, and lastly, to an increase in the granularity of vertex detectors. 3D detectors have an inherent good resistance to radiation damage that have allowed, after several years of R&D, to push their radiation hardness up to the...
Future new high luminosity colliders will require exeptionally radiation hard detectors, in particular those that will be closer to the interaction regions, i.e. tracking and vertexing detectors. The TimeSPOT R&D project has developed a new family of 3D silicon pixel sensors with 55 μm pitch that have shown an incredible time resolution of about 10 ps thanks to their new “trench” design. In...
In the new era of LHC experiments, fast-timing detectors are becoming a major priority. The LHCb upgrade II shall implement 4D tracking, enabling primary vertices spread in time to be distinguished, while maintaining high spatial resolution. Within VELO detector, a temporal hit resolution of 50ps within pixels of pitch < 50um is required. These demanding requirements necessitate a shift to...
